I'm liking the state capitals for regional. 50 state capitals and 100 aircraft. Spirit of Austin #2 :p
I gave space for 100 aircraft, but I probably won't have more than 50 regional planes lol. And it's North American province/state capitals, which includes Canada, so it's more like 61 or so.
I designated 50 tail numbers for concorde even though I have no intention to own 50 concordes....
